Eaton N390B-27M-1X2AP 27M OS2 8-Fiber MPO Breakout Cable

Split an 8-fiber singlemode backbone into two 4-fiber branches while maintaining a single APC MPO female connection at the trunk side. Eaton N390B-27M-1X2AP is a 27 m OS2 8.3/125 fiber breakout cable with one 8-fiber APC MPO female end and two 4-fiber breakout legs. Its fiber count and split geometry support structured fiber runs that need to fan out one higher-density cable path into separate four-fiber connections. The 27 m assembly suits equipment-room, telecommunications-room, and cross-room fiber routing where the required cable path is longer than a short rack jumper. The breakout construction lets installers route one 8-fiber trunk section for most of the path, then separate it into two four-fiber branches near the destination. This arrangement can reduce the number of individual fiber runs required along the shared portion of a route while preserving separate branch paths at the far end. OS2 8.3/125 singlemode fiber distinguishes this cable from multimode breakout assemblies intended for shorter optical runs. The specified APC MPO female interface is an 8-fiber connection, while the opposite side is arranged as two 4-fiber breakout legs. Verify route length, fiber-count requirements, connector mating requirements, and the needed branch arrangement before selecting the cable for an installed fiber pathway.
